Humankind has been performing the use of metals in a diverse area and applications. Earlier times, humanity used these metals for producing hunting weapons and defending oneself. Nowadays applications extend their use in industrial area, multiple robotic equipment, defense ammo, etc. Therefore, we encounter use of lanthanum in many areas. Lanthanum is one of the rare earth elements. It is a soft, ductile, silvery-white metallic chemical element with symbol La and atomic number 57. Lanthanum was first found by the Swedish chemist Carl Gustav Mosander. When we examine benefits of lanthanum, we encounter interesting area. * Lanthanum element does not have commercial uses, but its alloys are so popular. Lanthanum is used in large quantities in nickel metal hydride rechargeable batteries for hybrid automobiles. Today, a Toyota Prius hybrid car on the road carries with it about 4.5 kg of lanthanum. These cars have nickel-lanthanum hydride batteries. Also, these batteries are about twice as ...
